ADJUSTABLE SUPPORTING-ARM. AND BOXING FOB, DISKS.

To all whom it may concern:

Be it known that 1, JOHN R. LONG, a citizen of the United States,residing at Apache, in the county of Caddo and State of Oklahoma, haveinvented certain new and useful Improvements in Adjustable SupportingArms and Boxings for Disks, of which the following is a specification.

This invention relates to new and useful improvements in adjustablesupporting arms and boxings for disks to be used in connection withcultivators or the like.

One object of this invention is the pro vision of an arm such asdescribed, which will support the boxing in the rear of the disk, insuch position and at such angle that the sand or loose earth will beprevented from working into the boxing.

Another object of this invention is the provision of a supporting armfor disks which holds the boxing in the rear of the disk and in suchposition that the earth, weeds or the like will be thrown awaytherefrom, consequently preventing the same from clogging between thesaid axle box and disk.

Another object of this invention is the provision of an arm and boxingsuch as described which will support a disk so it can be very readilyand quickly adjusted to any desired angle, and which can be turnedbeneath the said arm to throw the earth either to or from the row.

Still another object of this invention is the provision of an adjustableconnection between the arm and boxing, by means of which the spindle canbe raised to any angle and by means of which the grease cup will be heldso that the same will be forced through the boxing, manifestly keepingit oiled at all times, and tending to force anyforeign substance whichmight enter the boxing therefrom.

A further object of this invention is the provision of an arm and boxingsuch as described, which is so constructed and positioned that it willtake all of the strain from Specification of Letters Patent.

Serial No. 783,686.

With the above and other objects in view this invention resides in thenovel features of construction, formations, combinations andarrangements of parts to be hereinafter more fully described, claimedand illustrated in the accompanying drawing in which:

Figure 1 is a top plan View of my invention, Fig. 2 is a side elevationthereof, and Fig. 3 is a longitudinal sectional view taken through theboxing.

Referring to the accompanying drawings by similar characters ofreference, through out the several views, the numeral 5 designatesgenerally a portion of a cultivator frame, to which is secured anattaching clamp 6. An arm 7 is pivoted as at 8 to the forward end of theclamp, while the rear end of the said clamp is formed with a slottedsegment 9, for receiving a bolt 10, which passes through the arm 7 andadjustably supports the latter in any desired position upon the clamp 6,relative to the bar 5.

The rear end of the bar or arm 7 is oflset as at 11 to produce aresultant standard 12, which supports an angular casting 13 consistingof the vertical plate 14 and the horizontal plate 15. The vertical plate14 is pivoted at its lower end as at 16 to the standard 12 while theupper end thereof is formed with a slotted segment 17, which receives abolt 18, which extends through the standard 12 and adjustably supportsthe casting 13 upon the said standard.

A circular enlargement 19 is formed upon the free end of the plate 15and is serrated upon its lower face to engage the upper serrated face ofthe circular member 20. The upper face of this member 20 is beveledforwardly as at 21 so the underside thereof will be slanted upwardly asshown at 22 at an angle, as illustrated in Fig. 3 of the drawing. Theforward portion of the underside of this member 20 is formed with asleeve 23, which receives the spindle 24,

while formed at the rear of this sleeve is a pair of cars 25, whichengage the said spindle, further holding the same against movement. Aneye bolt 26 surrounds the spindle 24 and passes up through the members19 and 20 and receives a nut 27, by

-means of which these members 19 and 20 can be held against any relativerotation.

A reduced extension 28 is formed upon the forward end of the sleeve 28,with its end 29 in contact with the rear end of the boxing 30 which isenlarged as at 31 to receive the said extension 28. The boxing is formedwith an interior groove 32, which forms a circular recess for receivinggrease or the like.

The boxing 30 is formed with a peripheral flange 33 to which the disk34: is attached, while the forward end of the spindle 24 is formed witha head 35 which con tacts with the forward end of the boxing 30. Agrease cup 36 is threaded upon the forward end of the boxing 30 and hasa concaved inner end 37 for holding grease and an angular boss upon itsouter end for en gagement with a wrench or the like, by means of whichthe same can be rotated.

From the foregoing disclosures take-n in connection with theaccompanying drawings, it will be manifest that an arm and boxing fordisks is provided, which will fulfil all of the necessary requirementsof such a device.

7 It should be understood in this connection that various minor changesin the specific details of construction can be resorted to within thescope of the appended claims, without departing from or sacrificing anyof the advantages of the invention.

Having thus fully described this invention, what I claim as new anddesire to protect by Letters Patent is:

In a device such as described, the combi nation with a supporting means,of a sleeve carried thereby, a reduced extension formed upon the forwardend of the sleeve, the opening in said sleeve slanting upwardly towardthe reduced extension, a spindle carried by the sleeve, and adjustabletherein, a head formed upon the forward end of the spindle in advance ofthe reduced extension of the sleeve, a disk boxing upon the spindle,said boxing having a socket in one end thereof to receive the reducedextension of the sleeve, the opposite end of the boxing being in contactwith the head of the spindle,

said boxing being further provided with i an interior groove, and agrease cup carried by the boxing, as and for the purposes set forth.

In testimony whereof I afiix my signature in presence of two witnesses.
